New England Distribution

Non-native: introduced
(intentionally or
unintentionally); has become naturalized.

County documented: documented
to exist in the county by
evidence (herbarium specimen, photograph). Also covers
those considered historical (not seen in 20 years).

State documented: never been
documented from the
county, but known from the state. May be present. Or,
may be restricted to a small area or a habitat (alpine,
marsh, etc.), so unlikely found in some
counties.

Note: when native and non-native
populations both exist in a county, only native status
is shown on the map.

Sometimes Confused With

monochasial branches of inflorescence with internodes less than 6 mm long, tepals mostly 3.5–4.5 mm, and capsules more than 75% of the length of the tepals (vs. J. anthelatus, with monochasial branches of inflorescence with
internodes 6 mm or longer, tepals mostly 2.5–3.5 mm long, and capsules less than
75% of the length of the tepals).

Juncus anthelatus

Juncus tenuis
→ This rare hybrid has been collected from
ME (Haines 2001a). It resembles
Juncus anthelatus in its stature and tall inflorescence with long internodes. However, the internodes of the inflorescence are straight (rather than often curved or arching), and the capsules are more than 75% as long as the tepals (rather than shorter than 75% as long as the tepals).
